Abstract

Système d'alerte préventive d’approche d'un véhicule (1) automobile d'un virage, ce système comprenant : - un dispositif d’aide à la conduite apte à contrôler le déplacement du véhicule automobile ;- un dispositif de navigation apte à fournir pour une position du véhicule (1) automobile un premier vecteur de distances séparant la position du véhicule automobile d'une première pluralité de points de la route en aval du véhicule automobile ; un deuxième vecteur de courbures de la route (10) auxdits points;- un calculateur configuré pour générer, lorsque la courbure de la route est supérieure à une valeur seuil d'alerte prédéfinie en une deuxième pluralité de points successifs de ladite première pluralité, une alerte préventive de désactivation du dispositif d'aide à la conduite lorsque le véhicule automobile se trouve dans un tronçon de la route comprenant ladite deuxième pluralité de points successifs. Figure pour l’abrégé : Fig.2Preventive warning system for the approach of a motor vehicle (1) to a bend, this system comprising: - a driving assistance device capable of controlling the movement of the motor vehicle; - a navigation device capable of providing for a position of the automobile vehicle (1) a first vector of distances separating the position of the automobile vehicle from a first plurality of points on the road downstream of the automobile vehicle; a second vector of curvatures of the road (10) at said points; - a calculator configured to generate, when the curvature of the road is greater than a predefined alert threshold value at a second plurality of successive points of said first plurality, a preventive alert for deactivation of the driving assistance device when the motor vehicle is in a section of the road comprising said second plurality of successive points.
